AbstractA new series of 1,3,4-oxadiazole derivatives with a 3-chloropyridin-2-yl-1H-pyrazole moiety was designed, synthesized, and characterized. The results of bioassay against Helicoverpa armigera and Plutella xylostella indicated that some of the synthesized compounds showed remarkable larvicidal activity. In particular, the LC50 values of the most active compounds against P. xylostella were 46
摘要设计,合成和表征了具有3-氯吡啶-2--2-基-1 H-吡唑部分的一系列新的1,3,4-恶二唑衍生物。对棉铃虫和小菜蛾的生物测定结果表明,一些合成的化合物显示出显着的杀幼虫活性。特别是,对小菜蛾的最具活性的化合物的LC 50值为46.5、23.9和13.9 mg / dm 3,对棉铃虫的最有效化合物的LC 50值为88.3和69.5 mg / dm 3,后者比商品毒死rif稍好一些( LC 50 103.77 mg / dm 3)。还讨论了初步SAR。 图形概要
